About the System Communication
The FOCUS 200 PLUS provides the following for communication to the Customer Care Center (CCC):
•
A main built-in dialer.
•
An optional 472402A backup dialer.
•
An optional 472491 AC Communicator Module. See the AC Communicator Module section for
detailed information concerning this module.
U
L
For Listed fire central station (UL864/NFPA 72) applications, use either a LORRA alone, the main dialer
with the LORRA, or use the main dialer with the 472402A Backup Dialer. For Listed fire remote station
(UL864/NFPA72) applications, use the main dialer with the 472402A backup dialer. Telephone line
supervision is required for UL commercial fire alarm systems when a dual-line dialer is used for fire signal
transmission.
•
The system supports the 472402A backup dialer. The older version 472402 cannot be used with the
FOCUS 200 PLUS system.
•
The system supports either the AC Communicator or the backup dialer, not both.
Reporting Formats Available
The reporting formats supported by the FOCUS 200 PLUS system are:

A Successful Transmission
Below is the communication sequence whenever a signal is transmitted:
1.
The control panel seizes the phone line and dials the Customer Care Center (CCC).
2.
The control panel waits to hear a “handshake” frequency tone from the receiver to confirm that the
receiver is on-line and ready to receive its message.
3.
After the panel hears the correct handshake, it transmits its message.
4.
If the message is received and understood by the receiver, it transmits a “kissoff” frequency tone.
